The low volume bow issue seems to be a common point that I hear most about. Maybe I'll re consder that. I don't think I actually changed that much from Nick's S&G in that regard. It may look small because of the lack of upward swept bow. When I get time I'll post a comparison picture. I wisk I knew the exact bow and ster termination points for Nick's boat.

Don't ask me to calculate volumes and coefficients, I'm waaay too lazy for that right now! I'm just having fun. When I get in one of those analysis moods (I just noticed about the first 4 letters of that word) I'll sit down with paper and slide rule to investigate such numbers.

I actually think there's less rocker than the S&G I started from. This just reinforces Nick's notion that when you start tweaking you end up with a different boat that may not work well.
